Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional coating methods are used to deposit coatings on mold surfaces, then coatings can be formed, but the coatings are uneven and reactants are wasted
Solution Approach 1:
The filament assembly is divided into multiple filaments (e.g., 3-5 filaments) arranged in an array, with each filament contributing to coating different regions of the mold. This segmentation allows for more uniform distribution of reactive species and better control over coating deposition across the entire mold surface, resolving the contradiction between coating uniformity and reactant efficiency.
Solution Approach 2:
The system positions filaments at specific locations and orientations to target specific regions of the mold that require coating. The gas inlet ports are strategically positioned to deliver reactants precisely where needed. This local quality approach ensures uniform coating coverage while minimizing reactant waste by concentrating material delivery only where coating is required.
2Productivity
If conventional coating systems are used, then coating deposition can occur, but efficiency and throughput are limited
Solution Approach 1:
Multiple filaments are combined into a single filament assembly that can simultaneously deposit coating material across multiple regions of the mold. The system merges the functions of multiple separate coating sources into one integrated assembly, enabling parallel coating operations that significantly improve throughput and reduce total coating time while maintaining high productivity.
Solution Approach 2:
The filament assembly extends in multiple dimensions (e.g., vertically and horizontally) to cover larger mold surfaces simultaneously. By transitioning from a single-point or linear filament configuration to a multi-dimensional array, the system can coat entire mold surfaces in fewer steps, thereby increasing productivity and reducing the time required for complete coating deposition.
